Expression, purification, and improved antigenic specificity of a truncated recombinant bp26 protein of Brucella melitensis M5-90: a potential antigen for differential serodiagnosis of brucellosis in sheep and goats.

Antibodies produced in animals vaccinated using live attenuated vaccines against Brucella spp. are indistinguishable using current conventional serological tests from those produced in infected animals. One potential approach is to develop marker vaccines in which specific genes have been deleted from parental vaccine strains that show good immunogenicity and vaccine efficacy.

Identification and characterization of a virus-specific continuous B-cell epitope on the PrM/M protein of Japanese Encephalitis Virus: potential application in the detection of antibodies to distinguish Japanese Encephalitis Virus infection from West Nile Virus and Dengue Virus infections.

Background: Differential diagnose of Japanese encephalitis virus (JEV) infection from other flavivirus especially West Nile virus (WNV) and Dengue virus (DV) infection was greatly hindered for the serological cross-reactive. Virus specific epitopes could benefit for developing JEV specific antibodies detection methods. To identify the JEV specific epitopes, we fully mapped and characterized the continuous B-cell epitope of the PrM/M protein of JEV.
